# Analyzing of singlet fermionic dark matter via the updated direct detection data

## TL;DR

This paper re-evaluates the singlet fermionic dark matter model using recent direct detection data, concluding that current experiments have excluded this model entirely.

## Contribution

It provides an updated analysis of the model's parameter space considering the latest experimental constraints, highlighting its exclusion.

## Key findings

- The model is fully excluded by recent XENON100, PandaX II, and LUX data.
- The mixing angle between the Higgs and singlet is constrained.
- Updated direct detection data significantly restricts the model's viability.

## Abstract

We revisit the parameter space of singlet fermionic cold dark matter model in order to determine the role of the mixing angle between the standard model Higgs and new singlet one. Furthermore, we restudy the direct detection constraints with the updated and new experimental data. As an important conclusion, this model is completely excluded by recent XENON100, PandaX II and LUX data.
